I grew weary messing around with xml sitemaps.
I now just support 2 sitemaps -
One sitemap.html for my visitors, and
one sitemap.txt for Google and Bing - just a list of alphabetized URLs.
Google gobbles it up from Webmaster Tools within minutes of submission, and indexes new pages within a day or two.
On one occasion, Google gobbled it up INSTANTLY!
It takes days and days for Bing just to download the list.
